ARLINGTON MOORE, OF 'WORCESTER, MASSACHUSETTS, ASSGNOR T0 MOORE INVEN- TLONS .MASSACHUSETTS CORlirORATON, 0F WORCESTER, MASSACHUSETTS, A COROEATIN GF Application filed. February 8, 1923. Serial No. 617,711'.

erably the form of a pole, which may be.

provided with handles and is adapted to be rocked or oscillated back and forth, thus causing the wheel to turn. At the same time the device is well adapted to be pushed by the foot of the user or the user may run land jump on the footrest, holding on to the pole, and the apparatus may be made use of in a `:great variety of ways according' to the whim, caprice and ingenuity of the user.

The embodiments of the invention selected for illustration only, and not for limitation of the invention, are shown in the accompanying` drawings in which Fig. 1 is a side view of a pole monocycle embodying the invention; Fig. 2 is a cross-sectional view taken on the line 2 2, Fig. 1; Fig. 3 is a side view showing the monocycle being propelled by the pole; and Fig. l is a side view of a modified embodiment of the invention.

VWheel 10 may be of any construction, as a disk wheel of metal or wood, a spoked wheel, etc., a wheel with wire spokes 11 being illustrated. The channeled wheel rim 12 is preferably provided with a solid rubber tire 13, similar to those used on buggy wheels, and which may be secured in place in a variety of known ways. Various other forms of tire, as pneumatic, etc., may be used,'but the solid buggy wheel tire is deemed preferable. `Wheel 10 has mounted thereon an upwardly extending pole 14. Said pole 111i is mounted to turn freely with respect to the wheel in one direction and when rocked in the other direction to cause the wheel to rotate. ln the form shown, the pole 14 has a yoke 15 on its lower end, being secured thereto by screw joint 16, and the wheel 10 turns freely as on the bali bearing` 17 on the shaft 18 extending through the yoke 15. The form of driving connection illustrated consists of a ratchet wheel 19 secured to turn with the wheel 1() and a pawl 20 on the yoke 15 adapted to be depressed by gravity to enge fre the ratchet wheel 1S) and anse the wheel 10 to turn when the pole is moved in one direction, the pawl 20 ridingl freely on the teeth of' the ratchet wheel 19 when the pawl is rocked in the other direction.

"his actuating connection ig for illustration only and various forms of actuating,` gounections may be used, so long` as the rocking; of the pole in one direction causes the wheel to turn and the pawl or equivalent device to move back freely without affecting the wheel. The wheel is, of course, free to run ahead justas the pole is free to be turned back vardly with respect to the wheel, the pawl running freely over the ratchet teeth.

'llhe yoke i5 has a foot f-:upport 21 pivotally connected thereto, so that the. foot support may hangI therefrom. lin the form shown, the foot support 21 comprises a board Vor the like 22, which extends entirely around the base of the wheel 10 and has a central opening 23 formed therein, through which the wheel 10 may pass, and a. pair of vertically extending members 2d pivotallv secured to the arms of yoke l5, at 25, The pivotal connections 25, 25 between the yoke 15 and foot 'support 21 are arranged below the axle 1S of wheel 10, so that the weight of the user applied to the foot rest 21 serves to maintain the pole 14 in a noi mally erect position. l'nuse, the boy or other user stands on the foot support 21 and propels the device by rocking' the pole 14 back and forth, leaning or throwing` his body in appropriate direction to maintain balance, or he may coast, the wheel 10 turning freelv under ratchet 20, or he may actuate the del vice, partly in the manner iii-st described, and partly by striking a foot on the ground, or by running and jumping ou the foot rest, or in various other ways which will readily suggest themselves to the user. lt will be seen that as the pole Lt is pushed forward by the user there is a certain amount of lifting` of the footrest and the weight of the user which takes place due to the relative arrangement of 'the parts, and as the pole is retracted there is a corresponding gli Sib
